Abstract: One embodiment of a method used to form a floating gate for a memory device comprises forming a crystallization nucleus seed layer using a process comprising disilane (Si2H6), then converting the seed layer into a plurality of electrically-isolated silicon nanocrystals using a process comprising silane (SiH4). The method described uses lower temperatures than previous silicon nanocrystal formation with improved uniformity of the completed silicon nanocrystals.

Abstract: A resin system for making fiber-reinforced composites, which is obtained by dispersing a particulate resin material into a thermosetting resin matrix. The resin composition is combined with a reinforcing fiber material to form composites of high strength retention and resistance to cyclic fatigue upon curing. The invention also relates to composite materials and articles thereof.

Abstract: A method of increasing the amount of entrained vapor in fiber-reinforced resin composite materials, and in particular filament wound composites, wherein a particularly effective chemical foaming or blowing agent is incorporated into the resin matrix composition used to form the composites. The foaming agent creates vapor-filled voids throughout the resin matrix of the composite as it cures. The superior composites containing these vapor-filled voids demonstrate high burst strength retention and excellent resistance to cyclic fatigue. The invention also relates to composite materials and articles thereof.

Abstract: This invention is a partially or semi-cured foam used to form the pipe insulation. The semi-cured foam is very flexible and can be formed around a pipe for a long period of time after production. The semi-cured phenolic foam board of this invention is a closed cell foam. The semi-cured foam is further cured in the formed shape. Upon curing the foam retains the shape of the preform. The semi-cured product is very flexible, once fully cured, the insulation becomes rigid.

Abstract: The invention forms in situ carbon dioxide blown closed cell insulating foams in which blowing is achieved by the evolution of carbon dioxide resulting from partial hydrolysis of polyisocyanate (methyl diphenyl diisocyanate) by water in the resole. The invention uses no additional blowing agent. The reaction is fast and the resulting product has small, closed cells that exhibit long term thermal performance.
